Abstract
Acanthephyra curtirostris Wood-Mason, 1891 (Fig. 9Q–S) Acanthephyra curtirostris Wood-Mason, 1891: 195. — Faxon 1895: 164, pl. 43, figs. 25. — Rathbun 1904: 27. — Schmitt 1921: 33, fig. 19. — Chace 1940: 143, text fig. 21; 1986: 17, figs. 2i, 4i, 5i, 6g, 8h. — Goodwin 1952: 394. — Crosnier & Forest 1973: 39, fig. 8a. — Butler 1980: 61. — Méndez 1981: 89, figs. 273–275. — Krygier & Pearcy 1981: 81. — Hendrickx & Estrada-Navarrete 1989:114; 1996: 113, fig. 70. — Wicksten 2002: 135. — Hendrickx & Wicksten 2004: 140. Diagnosis. Rostrum triangular in lateral view, as long as antennular peduncle, with 6–9 small dorsal, 1 or 2 ventral teeth; extending posteriorly as carina on anterior 0.66 of carapace. Carapace with prominent carina extending posteriorly from branchiostegal tooth, grooves extending posteriorly from orbit, antennal region; also y-shaped groove on posterior lateral region. Eye small, pigmented. Antennular peduncle short, scaphocerite long, with lateral tooth exceeding blade. Third maxilliped stout, distal segment with longitudinal ridge. Pereopods 1, 2 short, chelate; pereopods 3–5 with simple dactyls. Abdominal somites 2–6 with strong dorsal carina, somites 3–5 ending in posterior dorsal tooth; third tooth strongest. Telson with truncate apex, 8–12 lateral spines, 4 pairs distal spines. Male total length 69 mm, female to 79 mm. Color in life. Crimson. Habitat and depth. Bathypelagic, 300–2000 m, greatest catches at 600–900 m, does not seem to migrate daily. Range. Indo-West Pacific, Vancouver I. to Peru, Gulf of Mexico and Atlantic Ocean. Type locality Bay of Bengal.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
